You will want your results to be well-defined and repeatable. To to this, you'll need to be working against known data so that you can clearly define both your normal cases and your boundary cases. In my work, this is always a specific server and dataset so the Unit testing module has the connection string built in. Others prefer using a connection string out of the Unit Testing project. I've never seen anyone recommend the use of the web site's config file! (development or otherwise)
